Abstract
Disclosed rotor assemblies can be configured to address differential thermal expansion in the rotor assembly during ESP motor use. Some rotor assembly embodiments can employ an improved stacking technique to minimize differential thermal expansion issues by removing certain components from the axial stack of supporting components of the rotor assembly. Alternatively, or in conjunction, some rotor assembly embodiments can use a biasing element which is configured to compensate for the differential axial thermal expansion, tolerance stack-up, and/or gravity.
